This invention discloses a method for recovering manganese from electric furnace ferromanganese slag, comprising the following steps: crushing and uniformly mixing the ferromanganese slag, then drying it; uniformly mixing the dried ferromanganese slag with flux, calcining it in a tube furnace until the reaction is complete, and after the temperature drops to room temperature, removing the calcined slag sample, adding deionized water to leach manganese sulfate at room temperature, filtering and separating to obtain crude manganese sulfate solution and leaching residue; adding metallic manganese powder, ammonium sulfide, and flocculant to the crude manganese sulfate solution to further remove impurities, then adjusting the pH, filtering and separating to obtain a four-stage purified manganese sulfate solution. This invention utilizes a mixed flux to sulfatate metal oxides, achieving higher sulfatation efficiency than existing technologies, accelerating the process of extracting manganese from ferromanganese slag to produce high-purity manganese tetroxide, while simultaneously solving the resource waste and environmental pollution problems caused by ferromanganese slag from electric furnaces.

The invention discloses a method for recovering manganese from electric furnace ferromanganese slag. The method comprises the following steps: crushing the electric furnace ferromanganese slag, uniformly mixing, and drying; the method comprises the following steps: uniformly mixing dried electric furnace ferromanganese slag with a flux, roasting in a tubular furnace, completely reacting, taking out a roasted slag sample when the temperature is reduced to room temperature, adding deionized water, leaching manganese sulfate at room temperature, filtering and separating to obtain a manganese sulfate crude solution and leaching slag; adding metal manganese powder, ammonium sulfide and a flocculating agent into the manganese sulfate crude liquid to further remove impurities, then adjusting the pH value, and filtering and separating to obtain a manganese sulfate fourth-time purified liquid; according to the method, the mixed flux is used for sulfating the metal oxide, the sulfating efficiency is higher than that in the prior art, the process of extracting manganese from the electric furnace ferromanganese slag to produce high-purity manganous-manganic oxide is accelerated, and meanwhile the problems of resource waste and environmental pollution caused by the electric furnace ferromanganese slag are solved.
